Universal Cleaner vs. Bathroom & Shower Cleaner: What’s the difference?Updated 13 days ago

Koh Universal Cleaner is built for breadth: a two-ingredient alkaline formula (potassium hydroxide and water) that handles grease, grime, and light soiling across 20+ surface types. Spray, wipe, no rinse needed. Koh Bathroom & Shower Cleaner is built for depth: a 12-ingredient enzyme-powered foam (including lipase, surfactants, and builders) that clings to vertical surfaces and breaks down soap scum, body oils, and hard-water build-up. Needs dwell time and a water rinse.

Use both, at different times. Koh Universal Cleaner is great for quick bathroom touch-ups: wiping basins, benchtops, mirrors, and toilet exteriors without rinsing. Koh Bathroom & Shower Cleaner is the right tool for the shower screen, tiles, grout, bathtub, and anywhere soap scum or body oils build up. The foam clings to vertical surfaces, the enzymes work on organic grime, and the rinse carries everything away clean. Many people use both: Universal Cleaner for midweek touch-ups, Bathroom & Shower Cleaner for the weekly deep clean.

Both Koh Universal Cleaner and Koh Bathroom & Shower Cleaner are Sensitive Choice approved by the National Asthma Council of Australia, Eczema Association of Australasia certified, fragrance-free, septic-safe, and made in Australia. Both come in bag-in-box packaging that uses significantly less plastic than traditional rigid bottles. Universal Cleaner additionally holds GECA eco-certification and Allergy UK approval. Bathroom & Shower Cleaner additionally holds Dermatest dermatologist-tested certification. The difference is purpose, not principles.
